Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

The present application provides a window assembly 1, please refer to fig. 1 and fig. 2 together, fig. 1 is a schematic top view of the window assembly provided in an embodiment of the present application; fig. 2 is a schematic partial sectional view taken along line I-I in fig. 1. The vehicle window assembly 1 comprises a vehicle window glass 11, at least two sensors 12 and a heating element 13, wherein the vehicle window glass 11 comprises a functional area 111, at least two signal transmission windows 1111 are arranged at intervals in the functional area 111, the at least two sensors 12 are arranged on the inner side of the vehicle window glass 11, each sensor 12 corresponds to the position of each signal transmission window 1111 in a one-to-one mode, the heating element 13 comprises at least one linear heating element 131, the at least one linear heating element 131 extends through at least one signal transmission window 1111 for multiple times, and no linear heating element 131 extends through at least one other signal transmission window 1111.

It should be noted that, in order to better observe the distribution of the sensor 12 and the heating member 13 under the window glass 11, the sensor 12 and the heating member 13 are shown in a perspective view in fig. 1. In the present embodiment, the sensor 12 includes at least an image sensor 12 capable of acquiring an image of the front of the window glass 11 transmitted through the signal transmission window 1111. In this embodiment, the signal transmission window 1111 has a trapezoid shape, and in other possible embodiments, the signal transmission window 1111 may have other shapes, such as a rectangle, a triangle, a circle, and the like, which is not limited in this application.

It can be understood that in bad weather such as rain, snow, frost, etc., the window glass 11 is easily fogged and frosted, so that the sensor 12 cannot clearly acquire the front view. Heating the window glass 11 can realize the effect of accelerating defogging and frost, so that the sensor 12 can acquire a clear front view.

It should be noted that the heating member 13 is a resistance heating element, when a current passes through the heating member 13, the heating member 13 will generate a certain amount of heat, and since the vehicle-mounted voltage is substantially constant, the amount of heat generated by the heating member 13 is generally inversely related to the resistance value of the heating member 13. Meanwhile, considering that at least a part of the heating member 13 passes through the signal transmission window 1111, in order to reduce interference of the heating member 13 with the image acquired by the sensor 12, the heating member 13 is generally selected to have a size as small as possible. That is, in the present embodiment, the heating member 13 has a suitable resistance value, which ensures that the heating member 13 can generate a certain amount of heat to heat the window glass 11 when the heating member 13 is powered on, and prevents the heating member 13 from interfering with the acquisition of the image by the sensor 12.

In this embodiment, one end of the linear heating element 131 is connected to a positive electrode of a power supply, and the other end of the linear heating element 131 is connected to a negative electrode of the power supply, so that a current flows through the linear heating element 131. The at least one linear heating element 131 extends through at least one of the signal transmission windows 1111 a plurality of times to heat the corresponding signal transmission window 1111 of the window glass 11. At least one other of the signal-transmissive windows 1111 has no wire-like heating element 131 extending therethrough, thereby allowing for a more rational arrangement of wire-like heating elements 131 while meeting the defrosting and defogging requirements of the particular signal-transmissive window.

It can be understood that, in the present embodiment, through the arrangement design of the heating elements 13, the linear heating element 131 heats the entire region of one of the signals passing through the window 1111, and heats the peripheral region of at least one of the remaining signals passing through the window 1111, so as to achieve the effect of simultaneously and differentially heating a plurality of signals passing through the window 1111, and have a better arrangement of heating regions while accelerating the defogging and defrosting effects.
